Parts for your 2018 Ford Focus-Cv boots

2018 Ford Focus CV boots — what they do and how to look after them

CV boots are absolutely fitted and relevant on the 2018 Ford Focus. The Ford Workshop Manual for the Focus (2012–2018, Section 205-04A Front Drive Halfshafts) details removal and installation of both inner and outer CV joint boots, and the Haynes Repair Manual for Ford Focus 2011–2018 also covers inspection and replacement of these boots. OEM parts catalogues for the 2018 Focus list inner and outer CV boot kits for each front driveshaft, confirming their use on this model.

On a 2018 Focus, the constant velocity (CV) joints on each front driveshaft are protected by flexible rubber boots packed with special moly grease. The boots keep the grease in and road grit, water, and dust out, so the joints can articulate smoothly through steering and suspension travel without wear. When a boot splits or a clamp loosens, grease flings out and contaminants rush in, which can quickly turn into joint noise, vibration, and eventual failure.

As part of regular servicing, it pays to have the CV boots checked at each service interval (typically every 12 months or 15,000 kilometres in AU/NZ conditions). A quick visual inspection for cracks, perishing, loose clamps, or grease spray on the inner wheel, strut, or undertray goes a long way. If a boot is only slightly cracked, proactive replacement of the boot and grease can save the original joint. If the joint has run dry or has ingested grit, replacing the complete driveshaft assembly is often the smarter call.

When replacing boots on a Focus, quality matters. Use genuine or high-spec boot kits with the correct molybdenum CV grease and new stainless clamps, cable ties are a no-go. Clean the joint thoroughly if it’s being reused, and pack the specified amount of grease. Refit with new hub nuts where required and tighten all fasteners to the Ford workshop spec. After reassembly, a short road test followed by a recheck for sling or seepage helps catch any clamp issues early.

• Tell-tale signs: clicking on turns, shudder under load, or fresh grease inside the wheel/guard.
• Best practice: inspect every service, replace boots at the first sign of damage, and don’t drive long with a torn boot.

Popular questions about 2018 Ford Focus CV boots

Do all 2018 Ford Focus models have CV boots?
All front‑wheel‑drive 2018 Focus variants use CV boots on the front driveshafts (inner and outer joints). Performance and special variants may have additional driveline boots where equipped. For mainstream models, front CV boots are standard and serviceable items.

How often should the CV boots be inspected?
They should be inspected at each routine service, typically every 12 months or around 15,000 kilometres in Australia and New Zealand. High kilometre drivers, vehicles on rough roads, or cars with lowered suspension should be checked more frequently due to increased boot articulation and exposure.

Is it better to replace just the boot or the whole driveshaft?
If the boot has only just split and the joint is quiet with no roughness, a boot kit and fresh grease usually does the trick. If there’s clicking, visible corrosion, or the joint has been open to dirt and water for a while, a complete driveshaft assembly is often more reliable and can be cost‑effective on labour.
